What are probiotics
According to the WHO’s definition, Probiotics are live microorganisms, typically bacteria or yeast, that give us health benefits when ingested in sufficient amounts. The most common species that we see in our supplement probiotics are strains of bifidobacterium and lactobacillus. Probiotics have many potential health benefits including:
supporting immune system
improving digestive function
increasing absorption of nutrients
preventing and treating UTIs
reducing symptoms of IBS and IBD
It’s important to note that most probiotics don’t colonise the gut i.e. set up shop and live there. They pass through the GI tract and play useful roles along the way, and help existing colonies of beneficial bacteria to grow and proliferate.

For most people, these side effects are short lived and just take a week or so of adjusting to introducing new bacteria.
